proposed tuner types incorporate the RF tuning function and the IF down conversion.
Usually the IF down conversion stage also includes a single channel and analog sound
FM demodulator. The Philips tuner FI1216 MK2 is dedicated to the 50 Hz system
B/G standard as used in Europe. The FI1236 MK2 is the comparable type for the 60 Hz
system M standard for the USA. Both types are suited for terrestrial broadcast and for
cable reception. The tuner provides composite video and baseband audio as mono or
‘multiplexed’ (mpx) in case of BTSC. These analog video and sound signals are fed to the
appropriate input pins of the SAA7130HL.
Further analog video input signals, CVBS and/or Y-C, can be connected via the board
back panel, or the separate front connectors, e.g. from a camcorder. Accompanying
stereo audio signals can also be fed to the SAA7130HL.
